MACHINE FR BURNISHING BOOTS AND SHOESB vSPIEKL'IFICATIQN forming part ofLetters Patent No.,334,39', dated January 12, 1886. Application filedOctober 17, 1885. Serial No. 180,161. (No model.)

To all whom it may concern:

Be it known that I, HUGH NELsoN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMachines for Burnishing the Button-Shanks and Top Lift-s of Boots andShoes; and I do declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of a side elevation of themachine. Fig. 2 is Fig. 3 is an enlarged sectional detail. Fig. 4 is across-sectional view taken on lines xx of Fig. 1, and Fig. 5 is a detailplan view taken above the gears E' and h.

This invention relates to improvements in machines for burnishing thebottoms, shanks, and heels of boots and shoes by rotary motion, its'object being to perform the work With ease and facility; and it consistsin the construction and novel arrangement of parts hereinafterdescribed, and pointed out in the appended claims.

Beferring to the'aceompanying drawings by letter, A designates the mainframe of the machine, consisting of the front part, A', and the'rearpart, A, as shown. The front part, A', rests upon two legs, and has uponits top two parallel rearwardly-extending plates, a a, between the endsof which is bolted the vertical plate a', which rises from afrontwardlyextending arm of the single leg of the rear part, A. Througha lug on the said leg near its bottom runs the bent stay-rod or brace B,the

,arms of which extend frontward and upward and pass through the legs ofthe front part, A', being held in place by the nuts b b on the threadedends, ,as shown.

O is the horizontal driving-shaft of the machine, turning in thebearing-boxes D D' on the respective tops of the front and rear parts,A' A, of the main frame. The lower part of the bearing or journal-box Dis fitted into a proper bed, groove, or recess in the part A',

and has its cap d bolted upon it. The lower part. of the journal-box D'is similarly fitted into the top of the part A2, and is similarlyprovided with a cap, d'. Both caps have oilholes on their tops tolubricate the bearings.

E is a fly-wheel on the rear projecting end of the shaft O.

E' is a bevel gear-wheel on its front projecting end, and e is acrank-arm on its rear end, outside of the fly-wheel.

F is a link or rod connecting the crank-arm to the rear arm of atreadle, F', which has its footplate on its front arm and is pivotedupon a transverse bar, f, which runs through rearwardly-projecting lugson the legs of the front part, A', near their bottoni, and is held inplace by the nuts f' on its threaded ends, there being a nut bothoutside and inside of each lug. By the described means the shaft O canbe rotated by foot-power. To rotate it by a motor, the shaft has apulley, G, secured on it between the'parts A' A, and a loose pulley, G',on which to run the belt of the motor when running the shaft byfoot-power.

Gr2 is a bearing or journal block composed of an outer and inner partbolted together, the bolts running into a plate, g, standinghorizontally outward from the front part of the main frame, and in whichthe inner part of the journal-block has its seat.

H is a Vertical shaft turning near its upper end in the journal-blockGZ, and having on said end above the block a bevel gear-wheel, h, whichmeshes with the bevel gear-EC h' is a circumferential shoulder on theshaft below the block, so as not to allow it to rise therein. Below theshoulder the shaft is enlarged, as shown, and on its lower end it has acircular head, h.

I is a sleeve, triangular in section, traveling upon the shaft H, andhaving the lower end of its base countersunk or reamed out toaccommodate the head hz. The sleeve has standing horizontally out fromthe upper end of its sides the three lugs or ears z' and from the lowerends of the same the similar lugs or ears, i' t' i is a coiled springsurrounding the shaft above the sleeve and bearing upon the latter andupon the journal-block G. The sleeve is caused to rotate with the shaftH by means of IOO a longitudinal slot, h, in the latter, and a pin, fia,passing through the sleeve and slot. Each Upper ear, i, and lower ear,i, has passing through them a Vertical finishing-tool rod, J, which hason its threaded upper end above the ear 'i a retaining-nut, j, and abovethe ear i' a collar, j', the squared side of which rests against theside of the sleeve, so that the sleeve cannot rotate as it slides up anddown with the burnishing-tool rod.

7'2 is a set-screw by which the collar is fixed at the desired positionin the said rod.

K is a coiled spring surrounding the burnishing-tool rod between thecollar and ear i, and acting against the same.

L is a burnishing-tool on the lower end of the rod J. The face or lowersurface of the tool L is slightly convex from end to end, and has itsedges rounded, and from the center of its upper surface rise the cars ZZ, between which the lower end of the rod J is pivoted. The three toolsare so hung that their inner points all look permanently toward theaXial line of the shaft H, as the rods J do not turn in the ears t' M isa gas-tube having a burning-point on its end arranged to discharge uponthe burnishing-tools while reVolVing. The tube M' comes from any propersource of supply, and the burning gas therefrom properly heats theburnishing-tools. The gear-wheel his made eonsid erably smaller than'thegear-wheel E, so as to speed the shaft H, or give it greater relativemotion.

It is evident that the number of rods J and burnishing-tools need not belimited to three; but that number is most convenient. When the shaft Crotates, the intermeshing gears E' and h rotate the shaft H, whichcarries with it the sleeve-rods J and burnishing-tools, and the coiledsprings 'iz and K allow the tools to raise and give them easy motionwhile passing over the leather.

In operation, a shoe is placed beneath the burnishing-tools, which, whenthe machine is in operation, are given a rotary motion. It will be seenthat when power is applied to the treadle or pulley G the main shaft Cwill be turned, and consequently the gear E thereon, which imparts asimilar movelnent to the spring-surrounded shaft H through the medium ofits gear h. Vhen the shaft H has been rotated, the sleeve I and theburnishers will also receive a simultaneous rotation, and the burnishersact upon the shoe.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

l. The combination of the main shaft, rotated by means substantially asdescribed, the Vertical rotating shaft actuated by the main shaft, andthe sleeve on and rotating with the Vertical shaft and carrying one ormore burnishing-tools, by means substantially as specified.

2. The combination of the main shaft, rotatedby means substantially asdescribed and having a gear-wheel .on its end, the Vertical shaft havinga gear-wheel on its upper end meshi'ng with that on the mainshaft,thesleeve sliding on and rotating with the Vertical shaft, the coiledspring bearing against the journal of the Vertical shaft and against thetop of the sleeve, the burnishing-tool rods passing through ears on thesleeve, and the burnishing-tools pivoted to the lower ends of said rods,substantially as specified.

3. The combination, with the main shaft, provided with the gear-wheelE', the Vertical shaft H, having the gear-wheel h and provided with thelongitudinal slot hi, the sleeve I, pro- Vided with the ears t' i' andpin i, the spring iz, depressing the sleeve, the rods J, passing throughthe ears of the sleeve, the Springs K, acting against the collars j',and the burnishing-tools L, pivoted to the lower ends of the rods A Jand their inner ends pointing to the axial line of the shaft H,substantially as specified.

4. The combination, in a boot and shoe burnishing machine, of a Verticalrotating shaft, and a vertieally-yielding sleeve arranged on the saidshaft, rotating therewith and carrying burnishing-tools, substantiallyas specified.

5. The combination, in aboot and shoeburnishing machine, of a Verticalrotating shaft a Vertically-yielding sleeve arranged on said shaft andfixed with relation to its rotative movements, and Vertically yieldingand adjustable burnishers carried by the said sleeve, substantially asspecified.

In testimony whereof I affix my signaturein presence of two witnesses.
